Kurus is a free financial-literacy studio. Instead of explaining the market at you, it hands you one: a play-money market with invented companies, where you find out what a dip, a margin call or forty years of compounding actually feel like. Then it explains what just happened, in plain English.

The game

32 written lessons, from what a stock is to margin calls and spotting scams.

Teachers: there is a classroom guide and a standards alignment covering all six domains of the 2021 National Standards for Personal Financial Education.

The rules this place keeps

1. It never tells you what to do with your money. Facts, math and history, never a suggestion. Nothing here is financial, investment, tax or legal advice, and no page will ever recommend buying or selling anything.
2. The money is paper and the companies are invented. Every ticker in the games is fictional and the parody is meant to be recognised as parody. Where real market data appears, it is labelled as delayed fact, never a signal.
3. Your plan stays on your device. Your Number holds what you own, and it is never uploaded: not to us, not to anyone. No account is required for any part of Kurus.
4. Free, and honestly free. No ads. No purchases. No subscriptions. Nothing sold to students. No data sold, ever, to anyone.
5. Anyone can play; accounts are 13+. The games and the lessons need no account. The only things that ask your age are the ones that collect a name or an email: a profile, a public leaderboard handle, email updates.

Who makes it

Kurus is operated by Serdar Gunduz, a sole proprietor. A mailing address is available on request at [email protected].

It is built and maintained by one person. That is worth knowing for two reasons: the no-advice rule is not a compliance decision taken by a committee, it is the whole point of the project; and when you email, a person reads it.

Get in touch

One address for everything: questions, bug reports, a school or district that wants to use it, a privacy request, or a rights concern.

[email protected]

Teachers, say which class and what you are teaching and you will get a straight answer, not a sales sequence.

For privacy requests specifically (seeing, correcting, or deleting what we hold) the Privacy Policy sets out your rights and how long anything is kept. Most of it you can do yourself in a tap: a Buy the Dip profile has a DELETE ACCOUNT button that needs no email to us at all.

The fine print
